Postmodern art : Jackson Pollock and abstract expressionism

Radical movements in modern art
In general Pop Art and Minimalism began as modernist movements: a paradigm shift and philosophical split between formalism and anti-formalism in the early 1970s caused those movements to be viewed by some as precursors or transitional postmodern art. Other modern movements cited as influential to postmodern art are conceptual art and the use of techniques such as assemblage, montage, bricolage, and appropriation.

Jackson Pollock and abstract expressionism
During the late 1940s and early 1950s Pollock's radical approach to painting revolutionized the potential for all Contemporary art that followed him. To some extent Pollock realized that the journey toward making a work of art was as important as the work of art itself. Like Pablo Picasso's innovative reinventions of painting and sculpture near the turn of the century via Cubism and constructed sculpture, Pollock redefined the way art gets made at the mid-century point. Pollock's move - away from easel painting and conventionality - was a liberating signal to his contemporaneous artists and to all that came after. Artists realized that Jackson Pollock's process - working on the floor, unstretched raw canvas, from all four sides, using artist materials, industrial materials, imagery, non-imagery, throwing linear skeins of paint, dripping, drawing, staining, brushing, essentially blasted artmaking beyond any prior boundary. Abstract expressionism in general expanded and developed the definitions and possibilities that artists had available for the creation of new works of art. In a sense the innovations of Jackson Pollock, Willem de Kooning, Franz Kline, Mark Rothko, Philip Guston, Hans Hofmann, Clyfford Still, Barnett Newman, Ad Reinhardt and others opened the floodgates to the diversity and scope of all the art that followed them.

In abstract painting during the 1950s and 1960s Color field painting, Hard-edge painting and Lyrical Abstraction emerged as radical new directions.
